12.5 NIT Carrier Identification
M6100 Boadcast Satellite Modulator> TS MUX >> NIT Carrier ID
The carrier identification is used to reduce RFI (Radio Frequency Interference). The NIT carrier ID
allows the satellite operators to identify and contact the source of interference quickly. The carrier ID
is implemented in the Network Information Table (NIT) of the TS, more specifically into the network
descriptors set of the NIT. This information is readable by any MPEG analyzer system, which makes
it easy to track the source of the carrier. The carrier ID contains the following information:
• Fixed identification of the source:
– Modulator Manufacturer;
– Serial number of the modulator;
– MAC address of the modulator;
• User configurable data:
– Descriptor Tag, this tag describes the carrier ID information in the NIT.
– Carrier Identifier, insert a logical name for the carrier ID;
– Telephone number;
– Geo Coordinates;
When using both DVB-CID and NIT-CID, make sure that the Geo Coordinates entered
are the same.
– User Information.
In case the incoming TS does not contain a NIT, a NIT will be generated except when
no null packets are available in the TS to insert the NIT.
Make sure that enough null packets are available in the TS to insert the NIT.
The configurable carrier data is inserted into the NIT when this functionality is
enabled. This means that the carrier ID of the incoming TS is replaced with the
information entered in the M6100 Broadcast Satellite Modulator.
